Console No Reward From Completing Poundemonium Multiple Times

[pizzajuice5000]

I've done Poundemonium at least 5 times, and received no reward. My friend had a similar issue, but managed to get it on his second try. I have a few screenshots of the end-of-round victory screen, but it won't let me upload them here. I could post them somewhere else if it's necessary. Also, I'm playing on the PS4.
